Henri B. Kagan and Kenso Soai won the Nobel Prize in chemistry Wednesday for their efforts to resolve mysterious mirror images in chemical molecules, a discovery that transformed modern medicine.
asserted
that → win → medicine
Many molecules of life come in versions that look alike but aren’t exactly identical, like right and left hands.
asserted
that → come → hands
One mirror image of the chemical carvone smells like mint, for example, while the other has a whiff of caraway.
asserted
other → smell → caraway
When designing drugs to treat diseases, scientists want to be choosy about which mirror image they’re getting.
asserted
they → design → image
They want the version of a molecule that’ll treat a cold, not the kind that’ll make the sniffles worse.
asserted
sniffles → want → cold
Kagan and Soai found ways to make chemistry pick a side, designing and manipulating reactions to produce the desired mirror image.
asserted
chemistry → find → image
“This is probably the coolest experiment in organic chemistry,” said Peter Somfai, a member of the Nobel Committee for Chemistry.
asserted
Somfai → say → Chemistry
“Taken together, the groundbreaking discoveries by Henri Kagan and Kenso Soai have reshaped our understanding of molecular chirality — how it is created, amplified and transmitted.”
asserted
it → take → chirality
The discovery enabled most modern medicines
Scientists paid tribute to Kagan and Soai’s groundbreaking work, which the Nobel committee described as a feat never previously achieved by anyone “other than life itself.”
asserted
committee → enable → life

“It might be difficult to say that this drug, or that drug, was developed using this,” Somfai said.
uncertain
Somfai → get → this
“I would say all of them, because we use this as a tool, we use this as an understanding, how to develop catalysts, how they function.”
asserted
they → say → catalysts
“Chirality” comes from the Greek word for “hand.”
asserted
Chirality → come → hand
In the 1980s, Kagan’s work showed there might be a way to design reactions to produce one form of a molecule over the other.
uncertain
work → show → other
Years later, Soai brought that dream to life.
asserted
Soai → bring → life
He created the first-ever chemical reaction to produce only one of a molecule’s mirror images, in what’s now known as the “Soai reaction.”
asserted
what → create → reaction
“The medicines we have today would not be possible without this chemistry,” said Rigoberto Hernandez, president of the American Chemical Society.
asserted
Hernandez → have → Society
Kagan, 95 years old and born in France, is affiliated with the Université Paris-Sud in Orsay, France, and Soai, born in 1950 in Japan, with the Tokyo University of Science.
asserted
Kagan → bear → Science
The French Academy of Sciences, of which Kagan is a member, congratulated the two scientists and expressed its pride in the prize.
asserted
Kagan → congratulate → prize
Neither the Université Paris-Sud nor the Tokyo University of Science responded immediately to AP requests for comment.
asserted
Sud → respond → comment
“I’m very excited to receive the very nice news,” Soai told the committee and journalists by phone.
asserted
Soai → ’m → phone
He said he was shopping near his home when he was reached by the Nobel committee.
asserted
he → say → committee
More Nobel prizes will be awarded over the next week
The Royal Swedish Academy of Sciences announced the winner in Stockholm.
asserted
Academy → award → Stockholm
Last year, three scientists won the chemistry Nobel for their development of new molecular structures that can trap vast quantities of gas inside, laying the groundwork to potentially suck greenhouse gases out of the atmosphere or harvest moisture from desert environments.
asserted
that → win → environments
This year’s prizes began with the Nobel for medicine, awarded Monday to three scientists whose work led to a tool that uses light to help unravel how the brain works.
asserted
brain → begin → light
The physics award Tuesday recognized a scientist’s efforts to demystify a rare group of neutrinos.
asserted
award → recognize → neutrinos
The literature prize is set to be awarded Thursday.
asserted
prize → set → ?
After Friday’s peace prize is awarded, the Nobel Memorial Prize in Economic Sciences will be announced Monday.
asserted
Prize → award → Sciences
